The leader summoned the group and told that the time has come to act and not genuflect.
Step 1: Meaning of the word.
"Genuflect" literally means to bend the knee (especially in worship). Figuratively, it means to show excessive respect, deference, or servility.
Step 2: Match with options.
- (a) Grovel → behave in an excessively humble or servile way → exact synonym.
- (b) Procrastinate → delay action (different meaning).
- (c) Renounce → formally give up (different meaning).
- (d) Incriminate → to accuse of crime (not related). \[ \Rightarrow \boxed{\text{Grovel is the synonym of Genuflect.}} \]
